EV charger site survey

A pre-installation survey for home and workplace EV chargepoints. Record the customer and whether a government grant applies, the parking and charger position, the cable route and its length, the supply, main fuse, earthing and consumer unit, other large loads and the signal for a smart charger. A PME supply prompts you to record how the outdoor chargepoint will be protected. Every question is listed below, and you can fill the live form in on this page.

What does an EV charger site survey check?

An EV charger site survey checks the parking and where the charger will go, the cable route and its length, the supply phases, main fuse, earthing arrangement and consumer unit, other large loads and whether load management is needed, and the Wi-Fi or mobile signal at the charger, because home and workplace chargepoints sold in Great Britain since 30 June 2022 must be smart. It also checks grant eligibility and permissions.

Last updated . Facts checked by the SiteSurvey team on 17 October 2026 against GOV.UK: electric vehicle chargepoint grants, GOV.UK: electric vehicle chargepoint grant for renters and flat owners, GOV.UK: regulations for electric vehicle smart charge points and IET Wiring Matters: BS 7671 amendment 1, section 722 and PME supplies.

Every question in the EV charger survey template

An EV charger site survey: customer and grant eligibility, parking and charger position, supply, earthing, consumer unit and existing loads, cable route, Wi-Fi signal for a smart charger and photos. 5 sections and 55 questions. Follow-up questions and guidance appear only when an answer calls for them, so the person on site never sees the ones that do not apply.

Make it your own: every question is editable

This is a starting point, not a fixed form. Once it is in your SiteSurvey account you can reword any question, add or remove questions, sections and answer options, and add your own logo, so it fits the way your team works and the jobs you do.

EV charger survey FAQs

Is there a grant for a home EV charger?

GOV.UK lists the electric vehicle chargepoint grant for renters and flat owners: 75% of the cost, up to £500, for people who own and live in a flat or rent and live in any home, with private off-street parking. Funding is confirmed until 31 March 2027, and the chargepoint must not be installed until OZEV confirms the grant. There is a separate grant for on-street parking with a cross-pavement solution, and the Workplace Charging Scheme gives up to £500 per socket at workplaces.

Does a home charger have to be smart?

Yes, if it was sold in Great Britain on or after 30 June 2022. The Electric Vehicles (Smart Charge Points) Regulations 2021 require private home and workplace chargepoints sold in Great Britain to have smart functionality, including the ability to send and receive information. The form records the Wi-Fi or mobile signal at the charger position and warns when it is weak.

What is the issue with a PME supply?

The IET explains that BS 7671 regulation 722.411.4.1 does not allow a PME earth to be used for a chargepoint outdoors, or one that could charge a vehicle outdoors, unless one of the methods it lists is used, such as a chargepoint with open-PEN protection or a separate earth electrode. When the earthing is TN-C-S (PME), the form asks which method will be used.

Do renters and flat owners need permission?

Yes. A renter needs the landlord's permission and a flat owner usually needs the freeholder's or managing agent's. The grant requires those permissions before applying. The form asks for them when the customer rents or owns a flat.

Why record other large loads?

An electric shower, electric heating, a heat pump or a second charger can add up to more than the supply can carry. The form records them with the main fuse rating, so the installer can decide whether load management or a supply upgrade is needed.

What photos should I take?

The charger position and cable route, and the meter, main fuse and consumer unit. They go in the same record as the measurements, so the quote can be priced without a second visit.
